`GS = f(vec( alpha ^o & "AS" ) , vec( beta ^o & "WS" ))`

Enter a value for all fields

The **Aircraft Ground Speed** calculator computes the ground speed based on the wind speed (WS), wind direction (β), a Flight Heading (α) and an Air Speed (AS).

**INSTRUCTIONS:** Choose units and enter the following:

- (
**α**) Flight Direction - (
**AS**) Air Speed. - (
**WS**) Wind Speed. - (
**β**) Azimuth of the wind direction

**Ground Speed (GS):** The calculator returns the ground speed in miles per hour. However, this can be automatically converted to other velocity units (e.g. kilometers per hour) via the pull-down menu.
